Scaling a three dimensional model using a reflection of a mobile device

Abstract

A computer-implemented method for scaling a three dimensional model of an object is described. In one embodiment, first and second calibration images may be shown on a display of a mobile device. The display of the mobile device may be positioned relative to a mirrored surface. A reflection of an object positioned relative to the mobile device may be captured via a camera on the mobile device. A reflection of the first and second calibration images may be captured. The captured reflection of the object and the captured reflection of the first and second calibration images may be shown on the display. A reflection of the displayed captured reflection of the first and second calibration images may be captured. When the captured reflection of the displayed captured reflection of the first calibration image is positioned relative to the captured reflection of the second calibration image may be detected.
